' eordanee with the invention.

Be it known that I, GREEN B. GAnmsoN, a citizen of the United States,residing at Myrtle, in the county of Oregon, State ot' Missouri, haveinvented certain new and useful Improvements in Agricultural lmplements;and I do hereby declare the tollowing'to bea full, clear, and exactdescription of the invention,` such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to an agricultural implement and more particularlyto the class of crushing and pulverizing machines. The primary object ofthe invention is the provision of a machine or implement of thischaracter bywhich the ground is prepared for the reception of 'seed bycrushing and pulverizi'ng clods and lumps of dirt and also by levelingthe earth when crushed or pnlverized. t'

Another' object ofthe invention is the provision of a machine ,of thischaracter wherein the construction is generally irnproved and is lightand compact, consistent with strenffth and durability, and also one thatmay be rnanutaetlned at a minimum cost.

, Astill further4 objecten. the invention is" the provision 'of a'machine of 'this character wherein the crushing and pul\'erizing"' rolllers may be moved into and out ot position for operation at the will ot'an operator or driverot' the machine.

lVith these and other objects in view the invention consists `in theconstruction, combination and arrangementot parts as will behereinafter' more fully described, illustrated in the accompanyingdrawings which disclose the vpreferred form or embodiment of theinvention, to enable those skilled in the art to carry the inventioninto practice and as pointed out in the claim hereunto appended.

In the drawings :mliigureI lV is a top plan View of an implementconstructed in af:-

Similar reference characters indicate cor responding parts throughoutthe several views in the drawings.

ln the drawings there is shown a crushing and pulverizing machinecomprising a center beam 8, terminating at its forward end in a dral'tpole 9, and secured to this beam 8, at opposite sides thereof are theinwardly converging forward extremities of .side

beams or bars 10, which latter are suitably braced and held inhorizontal alinement with the said center beam. Fixed to the center beam8,' and to the side beams 10 are alining bearings l1, in which ismounted a main axle 12, the latter formed with crank extremities 1,3,having stud journals 14 to which are loosely connected the usual groundwheels 15, to permit the travel of the machine through a field.

At opposite sides ot' the center beam 8, and between it and the sidebars l0, are di sposed crushing and pulverizing rollers 1G, which latterare loosely journaled upon the axle l2, cach roller being ot' skeletonform and composed of spider heads 1T, connected by a plurality of bars1S, the same being angularly disposed -'with respect to the center draftof the machine and -formed with trunnion ends 19, engaging in theannular rims of the said heads whereby the said bars 1S are capable ofslight rotation 'fori the pur'- pose that will be hereinafter described.

Fixed to each bar 18, are a plurality of teeth 9.0, which are arrangedin spaced relation to each other and it is to be linderslood that. thenumber ot'; teeth may be increased or decreased depending upon the sizeand capacity of the implement and the character ot land upon which it isto be used. 'lhe teeth are wedge-shaped and have their penetrating endsmade rounding so as to provide approximately spade-shaped edges to theteeth.

l'utegrul with the axle 12, within the rollers ll', are spacedextensions 2l, the latter supporting' a roller 22, which extends uponrotation ot' the rollers lo the arms 23,t

will 'frictionally engage the roller 22, so that the said arms willetlect a change in the direction of the teeth 20, when leaving the earthlo lift the soil during the advancenlent ot the machine. Connected toopposite sides ot the arms 23, are springs 24, which latter are alsoconnected to the annular'rims oi' the heads 17, of the rollers wardlycurved resilient bracket arms 25, on

which are swiveled suitable brackets inV which are journaled gage wheels26, and these arms 25, are connected by a tie rod 27,

- having centrally connected thereto one end of a cable 28, the samebeing trained over a pulley 29, suitably journaled at the rear end ofthe center beam 8, and this cable 28, has its opposite end connected toa throw lever 30, rigidly-fixed to' the axle 12, adjacent the centerbeam 8, the said throw lever 30, carrying a locking pawl 31, engaging atooth segment 32, fixed vertically upon the center beam 8, of themachine. The said throw lever is adapted to turn the axle-12, to eitherraise or lower the ground wheels 15, or the crushing andpulvevizingrollers 14, toward or away from the ground. Also this throwlever is adapted to regulate the lgage wheels when eilectino` the raisinand L, t, D

lowering of the ground wheels and crushing and pulveriziug rollers ofthe machine.

In operation, presuming that the ground wheels have been raised, in themanner as heretofore stated andrthat the crushing and pulverizingrollers have been brought into contact with the ground, the machine isadvan ced upon the ground which will cause the teeth to penetrate intothe soil andA during the advancement of the machine these teeth willlift the soil and -at the same time break and crush the clods and lumpsthereof. As the spider heads 17 are rotated the bars 18 will be rockedby engagement of the rods 23 with the roller 22 so that the teeth 2O ofsaid bars 18 will break up the soil lumps or clods.

From the foregoing, the construction and operation of the invention willbe clear without the requirement of a more extended explanation, andtherefore the same has been omitted. 5

The combination with anl axle having crank arms formed thereon,supporting means carried by the crank arms, spiders mounted upon theaxle and arranged in spaced relation to each other, rocking barspivotally mounted on the spiders, said rocking bars being 'provided withpulverizing teeth, rods secured to the rocking bars and projectinginwardly therefrom, a roller mounted upon said axle for actuating therods and rocking the bars, and means for rocking the axle whereby therocking bars are brought into and out of engagement with the earthsubstantially as and l'or the purposes set forth.

In testimony whereof, I my signature, in presence of two witnesses.
